Remove hidden data from a PDF
Clean invisible document data before you publish, privately.
Publishing a PDF can leak more than the visible pages: the hidden document properties can reveal who made it, when and with what. This tool clears that hidden data in your browser, so the file is never uploaded.

Why clean hidden data locally
The hidden data you want gone should not have to be uploaded to remove it. Cleaning in the browser keeps the document on your machine.
Frequently asked questions
Is redaction the same thing?+
No. Redaction removes visible content you black out. This removes invisible metadata. For a full clean, use both.
Is my file uploaded?+
No. Cleaning runs in your browser and the file never leaves your device.
Should I do this before publishing?+
Yes, cleaning metadata before a document goes public avoids leaking who made it and when.
Is it free?+
Yes, with no sign-up.
